f u DUMPING can@ Application Ied November This invention relates to improvements in railroad dumping cars of the type in which the body of the ear is dumped or tilted with Vrespect to the sills and supporting truck, to discharge the contents of the car, and has for one of its objects the provisionv of iml "proved 'mechanism for tilting the car and which mechanism is operated by iluid pres- ',sure, the fluid pressure being under the vcon- "trol'of valves' located in a convenient position or in the engine cab.

To the attainment of these ends and the accomplishment of other new and use t'ul objects .as will appear, the inventionconsists intheffeatures of novelty in substantially the'construction, combination and arrangementjof the severalparts hereinafter `more ully'describedand claimed and shown Ainv nism therefor.Y l y l Referring morel particularly 'to the drawings thedumping car to which this invention y -is adaptedto be applied, is ofthe type consisting of a body 10 pivotally supported on a central longitudinal 'axis spaced below the floor of the4 body and thefulcrum is preferably formed bymeans osta-ndards or upricrhts 11 supported bythe sills 12 above the trucks 13. l f f `Any number-of lthese standards? may be employed and mayrbe of any desired height i according-to the height that'the body is i disposed abovethe sills. The body is pivotally connected with' the'standards 11 'b Asuitable ears I15 depending Jfrom the cai bottom and also through the uprights 11.

Supported by the sills 12 in Vany desired or suitable manner'preferably beneath the' sills is a supporting member'l, which pro-L jects laterally ybeyond 'the sills and terminates adjacent the opposite sides of the car body' 10. Telescoping cylinders'l? and 18 are providedfor tilting the cartbody about itsp'ivot 14." f The cylinder lis pivotally supported as at v19 upon the member. and

Figure l3 is ay diagrammatic'view of thelocking mechanismand the operating mechaas, '19824; serial No. 752,612.`

lwithin-the cylinderl? isv a piston 20, having 'l connected therewith a piston rod 21, the lat-v tcr extending throughthe'top of the cylinder 18 and is pivotally connected as at 22 withl a bracket 23secured to the car body 10.`

pOne of these cylinder devices is arranged c adjacent eachside of thecar andon vopposite sides of the sills-'12. Anynumber of Vcylinders may be provided, butin the yform of the-'invention shownherein, `fourcylindersare employed, two'of the cylindersbeing "disposedadjacent each of the ends ofthev car body. 4

`When luidis adniittedinto the cylinders beneath the piston 20 this piston will be rs't movedin the 'cylinder 18, therebyrocking.

the car 'body yaloout'its pivot 14. As soon:l

as the piston'20 reaches" the limit'ofits outward movement the fluid in thejcylinder 17 t will then move the cylinder. 18 outwardly from lthe cylinder-17, ,the car body being tiltedr according yto thev particularI cylinder" devices which-are rendered activeg l By the yarrangementfot the telesco'ping cylinders, together with; the piston 20, it will be manifest that the vdumping. mechanism may be .arranged within .the minimum and ai very compact space-,1V and .at the samel time the telescopingcylinders will permit, of any desired degree of movement of the car body about its pivot-1 The Ipivotal `connectionv 19 of the cylinder `171.-.with the supporting member 16 permitsthe cylinders andkpiston' rod to rock to correspond .to the dumpingv move- ,ment ofthe car-body,f so asnot to .interfere y, lwith the dumping operation and the right- "ing movement of the' `car body.

raid may be admitted into the @yiider i l17 from any suitable'sourcethrough aisupber of flexible pipes 25y may bexconnected to ply pipe 24, to which supply-pipe any numlead to the dumping mechanisms on one side" toi the carl body. :The dumping mechanisms ron the other side ofthe'car `body may be *supmeans of pivot pins 14 which pass througi plied with-fluid `through a similar pipe Yand e similar connections. I

The flow of iuid through the pipes may be controlled by any suitable valve mechanism (not shown) r andi located in any convenientpositionon the car or in'theengine Calb.`r-l 1 :inders onv voneside'of the car ity willbe eX- hau'sted lfrom .they cylinders orr the oppositeside of the car seras to allow the' car body te be swung in one directionabout ,its pivot.

When it is desired to return the car body the fluid is exhausted lfrom the active cylinders and admitted vinto the inactive cylinders.

Any suitable means lmay be provided for locking the car body aga-inst accidental,

y movement about its pivot and for that purpose-may .be provided any number offhangvers or sector elements, vwhich are secured vto thev car ybody andwvhich preferably pass beneath rvthe sills 12. The element 26 is preferably provided adjacent the front end of thebody and is provided with lugs 27 projecting 'laterally therefrom and ladapted toco-operate vwith suitable locking pins each: of whichis adapted lto -be normally projected by means of a spring 29 so that when the ylugs/27fare-Gmoved'into the proper position 'with respect Lto the locking pins, the latter` 'will co-operate therewith to hold fthe car against rocking movement. v

A suitable lever -30 'is pivotally mounted intermediateV its ends as at 31l and is connect- :ed' at one extremityas at; 32 with-a vpin 28 on .one side .of the car. To the-,other end of `the lever'30 is connectedfa bar or rod 33 and thisl bar or rodis connectedby a pin and slot connection 34-344with a cross vbar orlever 351,2the latter being pivotally mounted intermediatefitsf ends as ati36..

' Thewbar .or lever 35. is connected as at 37- with a piston rod 38. of apiston 39 that moves-:in a cylinder 40.' The rear pin 41 on/ the same Jside of 'checar as the pin 28,'and

' whichco-,operates with the rearhangenor sector member: .42, lis pivotally `connected as at 43jwith a lever 44,'the-latterbeingpivotally; mountedfintermediate its endsi as at 45.

Connected lwith the other end of the bar or lever 44 as at 46 isa rod 47; which-,is also connected awith they leverx35- and is provided witha slot 47a` Jfor the lreception of the ,pin l34. On theopposite side ofthe car the lock-` ing pin 48 .at the front {ofthezcar isipivotally connected asiat 49Jwith -a bar or lever 50, the

' latter" being pivotally. mounted intermediate its ends as at 51, and a bar or rody 52 is pivotally connected .with the lever at one end asat 53 and at-its other end .by a ,pin and slot` connectionv54f54a with thek lever 35. The

pin 55 at the rear ofthe car and on the samev side` as the pin 48 is pivotally connectedas at 56 with a lever 57 pivotally mounted intermediatel its ends as at, 58,.- and ,pivotally' cony .nected as at. 59 withthe lever 57 isl one end of a bar or .rod` 60,. iwhich .latteris also pivotally connected with fthe vlever 35. throughthe medium of a slot 60a which receivesthe pin .154.v

With ythis construction vit will .be noted that when the leverl 35 is rocked .about itsa pivot- 36', one ofthe locking pinsatzthe front.

of, the body on one side thereof and one of the locking pins at the rear of the body on theother sidefthereof will beloperated or v rendered active while the other pins will be rendered inactive, and vice versa. v

The pins 41 areadapted to respectively co- .operatefwith lugs 61 and 62 on the rear sector or hanger vmember 42.

The piston 39aisadapted to be moved in one direction in the cylinder 40 by means of liu-id supplied-to the cylinder through a suitable pipe' 63 lead-ing 7from a suitablesource of supply.- Fluid may also be Supplied'to n the opposite side ofthe piston will be I for-ced therefrom through {the respective pipes 64 63.. l

By the-operation of thevpiston39'the locking pins 28 `and 55 will be retracted to permit the car body to be-` swung labout its pivotl inqone direction, and the-vmovement of the piston 39 in another-'direction in thev cylinder willjretractA the pins 43 and 4l` and permit the 4pins 28-.and 55 to assume,-their-,normal positions, to permit the car body to beswung in the opposite, direction about 'itsspivot While the preferred form .of the invention has been herein shown anddescribed, it is to 4 be understood that variousV changes may f be made in the details of construction andin:
